What are the characteristics of photovoltaic chip/solar panel laser etching

Photovoltaic power generation is a technology that uses the photovoltaic effect of the semiconductor interface to directly convert light energy into electrical energy. The key component of this technology is the solar cell. After the solar cells are connected in series, they can form a large-area solar cell module, and cooperate with power controllers and other components to form a photovoltaic power generation device. The photovoltaic system has the advantages of being safe and reliable, noise-free, low-pollution, no fuel consumption, on-site power generation without the need to set up transmission lines, and short construction time. In today's society, against the background of overall energy shortages, energy conservation and emission reduction, the photovoltaic industry has made great progress. Today we will introduce the key equipment in the production of photovoltaic chips - laser etching machine!

Laser etching machine can etch 20nm power generation coating separately without damaging the bottom power generation coating and the middle nano layer. The etching edge can be controlled within 2nm to ensure that the bottom power generation coating and the bottom nano layer are not integrated. The machine can also etch 2 layers or all of them at the same time to achieve the effect of chip power generation!

The equipment is equipped with an automatic image positioning system, environmental safety and anti-static system, which provides guarantees for the fully automatic high-speed etching, cutting and high-quality stable operation of the product. The application of the modular integrated feeding mechanism of the etching function effectively improves the processing efficiency, and the adoption of the fully automatic processing mode effectively saves labor costs and improves product efficiency.
